These 50 Amazing Space Facts Will Completely Blow Your Mind

Space is an absolutely awesome place. The expanse of the universe is almost incalculable, and the wonders it holds are even harder to imagine. From a galactic-style kegger, to the most massive structure known to man, let’s take a look at some of the most amazing things that us humans have found. what is space science called space science definition what is space science and technology space science pdf

1. Mars has the biggest volcano known to mankind

Olympus Mons on Mars is the biggest volcano that we know of. The volcano stands a staggering 16 miles tall and is 374 miles across. That is three times larger than Mount Everest, and about the size of Arizona, respectively. what is space science called space science definition what is space science and technology space science pdf

Volcanoes on Mars can grow to this size because Mars doesn’t have tectonic plates like the Earth does. Don’t get too excited to see a massive eruption, though. Mars’s core has cooled, and it is believed that all volcanic activity has ceased to exist. what is space science called space science definition what is space science and technology space science pdf

Suffice to say, there are a zillion stars in the known universe. And in this case, the word “zillion” is just a fancy way of saying “uncountable.” what is space science called space science definition what is space science and technology space science pdf

3. Cold welding

When two like metals bump into each other in space, they will fuse together on their own. This process is called cold welding. It’s not possible in the atmosphere of Earth because there are other elements that keep them separate. Just imagine what this could mean when you are building a spaceship in orbit.
